My epson movie mate 55 dvd projector keeps telling me no disc when i put dvds in ?

Choose DVD-R (as opposed to DVD+R). The brand name won't matter, as long as they're obviously not unreliable rip-offs.

Problems having to all DVDS movies discs u have?Tries more DVDS movies watching.This problems u discribing right now,might causes by only one movie disc the DVD disc itself is probally the causes of this problem.

The solution is simple.I rang LG service (so called - LOL)
Asked for a fix or reset method. (Which can be done but they won't tell novices how)
Got no joy, so now I will bin it,and spend the rest of my days telling people to avoid LG.
After all the posts I have since read about the same problem on various LG models,it is obvious their product sucks,they know it does, but won't accept the responsibility.
If I stop 4 people buying their ****,that's at least $1000 they miss out on.
If the process snowballs,how much then$$ ?
It would cost me $120 just to get it to and pick it up from the repair place.
Plus parts and labour added.
Before buying an LG DVD recorder go online and check out how many dissatisfied customers there are. In short, DO NOT BUY !!

No, they cannot interchange.

I got two new disks to-day with pictures taken from 35mm slides. They will not play on my zenith znd400 dvd player. I wonder why??????

You have to make your DVD region free.

This is one possible solution:

Careful as it may or may not work.

I have the very same issue. The dvd player makes a clicking sounds, spins, then stops...no disc. I have tried cleaning it and have also tried new dvds.

Possibly a bad, or more likely, a damaged disc.

It's not uncommon, especially with often abused rental copies.

Tell Blockbuster - they should give you a credit on the rental.

My initial IDM-1731 tells me no disc every time i try to play dvd cd please help me

If this unit has a built in DVD player, then the player's lens may need cleaning. There are lens cleaning discs available for this. If the unit does not have a built in player, then the same applies to your player & there is no problem with the projector itself.
